<p>A navigation apparatus to be mounted on a mobile body. The apparatus includes an input device (1), a central processor (2), a display (3) and a memory (6). When the present position of the mobile body and a destination are given to the central processor, the processor produces at least two possible routes to the destination from the present position using data stored in the memory such as a map, and displays the present position (21), the destination (22) and the possible routes (23, 24) on a screen (3a) of the display. The preparation of at least two possible routes is effected by a processor (4) and computation/retrieval means (5). Connecting routes (25) existing between two or more possible routes can be retrieved and displayed. Furthermore, a possible area (26) inclusive of the possible routes can be retrieved and displayed. <IMAGE></p> |
